Upgrading from Earlier Versions of Integrity VM

If the HP Integrity Virtual Machines software is already installed, you can install the new version on the VM Host system without removing the existing software. Guests and guest applications are shut down but they are not otherwise affected when you upgrade Integrity VM. This procedure reboots the VM Host system.

If you have previously installed the Integrity VM product:
1. Back up the /var/opt/hpvm directory to retain existing Integrity VM configuration files. When you install Integrity VM, the guest and virtual switch configuration files are modified in a way that makes them incompatible with the previous version. This step allows you to drop back to a previous version of Integrity VM, if desired.
2. Log in to each guest on the VM Host and shut down its operating system. The installation procedure will stop any running guests, but it is preferable to shut them down manually before you start the installation procedure.
3. Identify the media from which you are installing the software.
  If you have installation media, mount it.
  If you are installing from the network, identify the system and path name corresponding to the HP-UX software depot that contains the Integrity VM software. (For example, my.server.example.com:/depot/path.)
Use the swinstall command to install the software.
- If you are using the command line interface, specify the path to the software depot. For example, the following command installs only the Integrity VM software:
  # swinstall -x autoreboot=true -s my.server.example.com:/depot/path T2767AC vmProvider
- If you are using the installation graphical interface (GUI), perform the following steps:
  Enter the following command:
  # swinstall
  Select the T2767AC bundle from the list presented by the GUI.
  This command installs the latest version of Integrity VM from the software depot.

If the VMProvider bundle is to be installed or upgraded, specify it when you install the new version of Integrity VM, or install it separately.

For example, if VMProvider is in the list, you can include it in the command to install the current version of Integrity VM:

# swinstall -x autoreboot=true -s my.server.foo.com:/depot/path T2767AC vmProvider

Installation of the current version of Integrity VM fails on systems that have older versions of the VMProvider bundle. The swinstall session fails and logs messages to /etc/rc.log indicating that a new version of VMProvider must be installed before or at the same time as Integrity VM. The VMProvider bundle is available on the Integrity VM installation media. If you do not wish to install the new version of the VMProvider, you must remove the VM Provider before you install the current version of Integrity VM.

To see which bundles are installed, enter the following command:

# swlist | grep -i "integrity vm"

  T2767AC               A.03.50     Integrity VM
  VMGuestLib            A.03.50     Integrity VM Guest Support Libraries
  VMKernelSW            A.02.50     Integrity VM Kernel Software
  VMProvider            A.03.50     WBEM Provider for Integrity VM

The VMGuestLib guest support libraries and the VMKernelSW kernel software are included with the HP-UX operating system installation.

The VMMigrate bundle shipped in earlier versions of Integrity VM has been merged into the T2767AC bundle and is installed or upgraded when T2767AC is installed.
Reinstall the guest management software on each existing guest, as described in the HP Integrity Virtual Machines Installation, Configuration, and Administration manual.
